From the manual: "The ET-3400 Microcomputer Learning System is a practical, low cost microprocessor trainer; designed as a learning tool to teach microprocessor operation, programming, and applications."
The breadboard areas allowed students to configure the machine for a variety of different experiments and tasks.
With the expansion chassis the memory was extended significantly and the input/output capabilities were expanded to allow the use of a terminal and cassette tape drive.
The device in my collection was donated by Mary-Anne Boulet.
